Is DLT registration mandatory and how do I get it?

Yes, TRAI mandates DLT registration for business SMS in India. Muzztech handles the entire registration — entity, headers and templates — free of charge, usually within 24–48 hours.

Can I send SMS from my own software?

Yes. Our REST and SMPP APIs integrate with any CRM, ERP or custom application, with code samples in PHP, Python, Java and Node.js.

What is the difference between promotional and transactional routes?

Transactional SMS (OTPs, alerts) deliver 24×7 even to DND numbers; promotional SMS deliver 9 AM–9 PM to non-DND numbers. We help you pick the right route so nothing gets blocked.
